Hard to believe I didn't see this sooner ,up on the pole barn but ,I don't use the light ,fixture is bad ,just haven't replaced in yet. I assume they are paper wasp's but not sure Blasted with wasp killer and again a couple hours later ,was cool today 65
They seem to come from nowhere don't they? One day nothing the next week big old nest. I have a big old vise in the lawn mower shed that is pretty good for replacing u joints and had been working on one on the 87 toyota drive shaft for an hour or so when a wasp flew out of the rafters and stung me on my back. Well I was done for the evening. I went back the next day expecting to see a big old nest hanging above where I was working and nothing. I got the u joint replaced finally, 27 years in a driveshaft makes for an adventure.
I spend time in late June here zapping golfball size nests that the queens have made. The cabin is especially good for hornets (yellow jackets)... lots of places for them to build a nest and no activity to bother them. I know what you mean about not seeing them sometimes. I found one this year here, on the inside of the door sill going into the garden shed. Can't believe I even saw it, they usually go for the roof. Wasn't really paying attention to lower areas. I will now.
Had one appear overnight under the front porch steps that we use all the time. Both of the new pups got stung , they are back door pups for now.
Last summer there was a nest in the ground near the wood pile that I discovered by "accident"-ouch. I didn't choose to fight and they relocated after the winter.
We recently had a mud wasp nest inside of a door jam in the shed. I ran. Then at night I sneak attacked them
Always trying to avoid "discovering" a big nest the hard way. I've found a lot of small ones that way...
I had a hornets nest inside my wall as big as a football--good thing it was deserted! My contractor found it when he had to open it up to install the front door. I had just moved there, so they were long gone, but the HAD to be audible when active!! Paper wasps generally speaking, are the ones that make the cellular type nests, the ones that grow in an umbrella shape. I learned the hard way to look before I put my hands under the ladder to lift it from the hook.
